Abstract

Linux is open source software which plays a major role in the Embedded OS landscape. It emerges as the platform of choice for many vendors of various sorts of equipment because of its scalability. Linux embedded development environment involves cross-compiling tool chains, Boot loader, Linux Kernel, C library, libraries and applications. The boot loader is responsible for loading the Kernel and initial RAM disk before initiating the process. This paper illustrates the step by step process of Transplantation of Boot loader (U-Boot) on S3C2410 is based on the ARM920T core of embedded general-purpose processors development board.

Abstract

A large number of serious or fatal accidents are occurred due to excessive or inappropriate speed of the vehicle. Distraction and drowsiness of the driver has been important factors for a large number of major accidents. They reduce the decision making capability and perception level of the driver which negatively affect the ability of the driver to control the vehicle. Monitoring the driver behavior is one of the ways to prevent the fatal accidents and it is necessary to alert the driver when they are drowsy or in a distracted state. With the new developed systems, there is a possibility of self controlling the vehicle when the driver was drunk or reckless or fatigue so that major accidents may be reduced. There is also a possibility of tracking the location of accident, if occurs, through Wireless Access Technology (GSM, GPS) so that proper measures are taken at correct time.

Abstract

The multiplier in any arithmetic unit dissipates a significant amount of energy as large number of computations are required if the number of bits in the design increase. Thus, if efficient reversible logic is used, then the power consumption can be reduced drastically as the information bits are not lost in case of reversible computation. This Paper focuses on the design of two-bit multiplier using a synthesis approach called Exorlink which reduces quantum cost compared to the technique Disjoint Sum of Products (DSOP). The design is coded in VHDL, simulated using ISIM and synthesized using Xilinx ISE 10.1i for the device Spartan3E FPGA.

Abstract

Nowadays data is transferred using internet from one place to other in whole world in its digital form. But data transfer using internet is a very risky affair and any third party can listen the information into network. These challenges encourage data hiding techniques like Encryption and Steganography. One advantage of steganography over cryptography is the cryptography protects the contents of a message only, whereas steganography can protect both messages and communicating parties. Mobile Apps Based Steganography Technique is comparatively new technique to hide secret information and has advantages of mobility, portability and high payload capacity. In this paper we are going to propose a generic solution for embedding data in a Mobile Apps Based Steganography Technique so that even a common user can use this technique for hiding his information inside a mobile application. This technique is implemented on J2ME platform; Mobile Application is a Maze game and it is tested on Nokia Supernova 7610 series phones.
